I have a color anodized piece that has some marks where a piece of soft
aluminum tubing rubbed against it. I'd like to remove the marks, but
don't want to damage the finish of the anodized part. The anodizing is
pretty heavy. I don't know how porous the anodizing might be, so I'm
leery of trying to etch it off.

Any tricks for this?

Thanks!
